【Grapes 4 major nutrients】:

anthocyanin:

Anthocyanins have extremely strong antioxidant properties and are a type of bioflavonoid. They have antioxidant and anti-inflammatory benefits, and help make blood vessels "softer". Anthocyanins are natural blue-purple pigments, so they are mostly found in fruits and vegetables, such as grapes, cherries, eggplants, etc. The health-promoting ingredients of grapes are mainly found between the skin and seeds, mainly polyphenols and anthocyanins. Among the four colors of grapes, the dark purple and black grapes have the highest content of anthocyanins, which can help fight aging.

Vitamin A:

Vitamin A is a fat-soluble vitamin that helps maintain normal vision and the integrity of epithelial mucosa, and also plays an important role in embryonic development. Commonly found in meat, dairy products and fish. Among the four colors of grapes, purple grapes contain the highest amount of vitamin A (24 mg per 100 g).

Vitamin B1:

Vitamin B complex is mainly composed of 8 water-soluble vitamins, including: B1, B2, B6, B12, niacin, nicotinic acid, biotin and pantothenic acid. It is the group with the most types and the most functions of all vitamins. It helps to accelerate metabolism in the body, provide energy and enhance physical strength. Vitamin B1 is found in grain germs, pork, whole grains, beans, offal, and fortified grains. Among the four colors of grapes, black grapes have a slightly higher vitamin B1 content (0.07 mg per 100 g).

Which color of grapes should I eat if I want to lower my blood pressure?

Another common myth is: "People with anemia must eat black grapes because they are the best for blood supplement." In fact, the iron content of a grape of any color does not exceed 0.1 mg, which is almost negligible. In addition, plant-based iron is not easy to absorb, so grapes are indeed not a good source of iron. Of course, they are not very beneficial for iron supplementation of blood.

As the saying goes, "Eat grapes without spitting out the skins." Why is that? And what should we pay attention to when eating grapes? Here are 4 tips for eating grapes that nutritionists remind you of:

【4 tips for eating grapes】:

1. Pay attention to the GI value:

Grapes are fruits with medium to high GI values. It is recommended not to eat more than 10 to 13 grapes (one serving) at a time. Especially those who need to control blood sugar should pay more attention to the amount!

2. Pay attention to potassium content:

Grapes are high in potassium, especially green grapes, which contain about 264 mg of potassium per 100 g. Kidney patients who need to restrict potassium should pay attention to this.

3. Wash before eating:

Grapes cannot be stored for a long time after being washed, as they are easy to spoil and lose nutrients, so first rinse the fruits with water, then cut them off with the stems (do not pull them out forcefully), and then soak them in running water for about 10 minutes before eating.

4. Eat grapes without spitting out the skins

Because antioxidant nutrients including anthocyanins and polyphenols are mainly concentrated in grape skins and seeds, you can eat them as long as you wash the skin.
